^it does have 50 series tires on it! so that makes it worse! i will be changing that soon with some 55 series!
the corroding part, i just sanded the area good. until it looked better, and cleaned the **** out of them!
as far as a tip, i sanded the rust off, cleaned them like 3 times with alcohol, and just paint brushed the paint on! i did use that hammered paint that is out now. no primer needed!
